Hellow, I want to create the reflection effect, I use the setEnvmapped but no effect. This effect maybe use the shader to performace, but I don't know how to write this and this may diffcult to me now , Could someone help me to give a sample shader to performace this effect, Thanks a lot!

If it helps, I can post a shader that I'm using for the gold nuggets in my game, but it's a little tailored to how the game handles light in dungeons, so I'm not sure if it helps more then it causes confusion.

Ok, so here you go. It's basically a modified default shader from jPCT-AE which skips the first light source (i.e. it starts with 1, not 0), because the 0 light source is used for another purpose in my dungeon rendering. The shader uses two texture stages. One for the environment mapping and one for the base texture. Anyway...

Sorry for my poor english, jpct-ae can inject data to textureUnit0,textureUnit1...textureUnit3, the value in shader, I means can I do this for my custom uniform texture in shader , e.g uniform mytexture

You don't. The texture units will be injected automatically. 0 represents the first texture stage, 1 the second etc. All you do is to assign your textures to your objects (look at TextureInfo for multiple textures stages on one object).

Thanks ! Could shader can perfomace the car light ? like the attached picture , If can , Could you give me a sample shader Thank you very much ! Or maybe there are another simple way to performace this effect , I have no idea...
